PFAS
Per- and polyfluoroalkyl substances (PFAS) are a group of human-made chemicals widely used in industrial and consumer products due to their water, grease, and heat-resistant properties. Found in items such as non-stick cookware, waterproof fabrics, food packaging, and firefighting foams, PFAS have been in use for decades.
Why Are PFAS a Concern?
PFAS are often called "forever chemicals" because they do not break down easily in the environment or the human body. Studies have linked prolonged exposure to PFAS with health risks, including hormonal disruption, immune system effects, and increased risks of certain cancers. These chemicals can contaminate drinking water, soil, and even the food supply, making their regulation and removal a growing global concern.
How Can PFAS Be Managed?
Due to their persistence, PFAS require advanced treatment solutions to be effectively removed from water sources and industrial processes. Technologies such as activated carbon filtration, ion exchange, and advanced oxidation processes (AOPs) have proven effective in reducing PFAS contamination.
At Ecosign, we provide cutting-edge water treatment solutions designed to mitigate PFAS pollution, helping industries and municipalities achieve cleaner and safer water. Contact us to learn how our innovative technologies can support your sustainability goals.
Current Best Treatments for PFAS for water

Advanced Oxidation Processes
-
An innovative technology that uses hydroxyl radicals to degrade PFAS into less harmful byproducts.
-
Can be combined with other methods for increased efficiency.
Ion Exchange
-
Uses ion exchange resins to capture PFAS from water.
-
More effective for short-chain PFAS, which are harder to remove with activated carbon.
-
Has a longer lifespan and can be regenerated in some cases.
Activated Carbon Adsorption
-
Granular activated carbon (GAC) is widely used to capture PFAS, especially long-chain compounds.
-
Effective but requires regular replacement to maintain performance.
Reverse Osmosis
-
One of the most effective methods, removing up to 99% of PFAS.
-
Uses semipermeable membranes to filter out contaminants.
-
Produces a concentrated waste stream that requires proper treatment.
How the Ecosign Multioxidative System Can Help Treat PFAS in Water
The Ecosign Multioxidative System is an advanced Advanced Oxidation Process (AOP) technology designed to break down persistent organic pollutants, including PFAS (per- and polyfluoroalkyl substances). AOPs are highly effective in degrading contaminants by generating powerful oxidants, such as hydroxyl radicals (•OH), which can break down the strong carbon-fluorine bonds that make PFAS so resistant to conventional treatments.
Integration with Other Technologies
The Ecosign Multioxidative System can be implemented in combination with existing technologies to enhance overall treatment efficiency:
🔹 Pre-treatment: Used before filtration systems (such as activated carbon or ion exchange) to reduce PFAS concentration and prevent overloading.
🔹 Post-treatment (Polishing): Applied after primary treatment to further degrade remaining PFAS or other residual contaminants.
🔹 Parallel Treatment: Used alongside other technologies to manage byproducts and secondary pollutants generated during PFAS removal.
With its flexibility and high efficiency, the Ecosign Multioxidative System offers a comprehensive solution for addressing PFAS contamination, ensuring cleaner water and improved environmental safety.
